Yesterday, I came across this little gem of a public API: Data Science Toolkit
From their web site:
A collection of the best open data sets and open-source tools for data science, wrapped in an easy-to-use REST/JSON API with command line,Python and Javascript interfaces. Available as a self-contained VM or EC2 AMI that you can deploy yourself.
Some examples of what their API provides:
Street Address to Coordinates
API: /street2coordinates
Street Address to Location calculates the latitude/longitude coordinates for a postal address.
Currently restricted to the US.IP Address to Coordinates
API: /ip2coordinates
IP Address to Location calculates country, state, city and latitude/longitude coordinates for IP addresses.
See their Developer Documentation for more details on using their services, or how to run your own Data Science Toolkit service.
